THREE-HORSE EVENER.

SPECIFICATION forming part of Letters Patent No. 758,745, dated May 3,1904.

Application filed October 29, 1902. Serial No. 129,241. (No model.)

To all whom it Wart/ concern:

Be it known that I, J osarn W. GAMBLE, residing at Omaha, in the countyof Douglas and State of Nebraska, have invented certain usefulImprovements in Three-Horse Eveners; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention, suchas will enable others skilled in the art to which it appertains to makeand use the same, reference being bad to the accompanying drawings,which form a part of this specification.

This invention relates to a new and useful improvement in three-horseequalizers.

The aim of my invention is to provide the combination of an equalizerwith a wagontongue so constructed that two horses will be upon one sideof the tongue and one upon the other, the equalizer being so constructedthat the load will be equally distributed between the threedraft-animals, so that the tongue will be advanced in a straight line.

In the accompanying drawings 1 have shown in Figure 1 a top view, withportions removed, of a wagon-tongue provided with my threehorseequalizer. Fig. 2 shows a perspective view of the spool-bracket as usedin my invention. Fig. 3 shows a sectional view disclosing thearrangement of the connection of the doubletree and one of theswingletrees. Fig. 4 discloses a side view of the clevis, while Fig. 5shows a broken view of the spoolbracket as used in my invention.

. The object of my invention is to provide a wagon or such otherimplement or vehicle as have tongues with a three-horse equalizer soconstructed that two horses are upon one side of the tongue and one uponthe other.

In constructing my equalizer I employ a doubletree 20, which near oneend is provided with an eyebolt 25, which by means of a link 26 worksinto an eyebolt 27, secured in a swingletree 28. Near the remaining endthis doubletree 20 is perforated, so as to receive the bolt 16, whileapproximately centrally is secured the bolt 11. Extending from the bolt16 is the upper clevis 18, which is bowed slightly upward to receive thebolt 17, while from below the doubletree 20 projects the lower clevis19, also secured to the bolt 17, and between these clevises 18 and 19 isheld the doubletree 20, as is shown in Figs. 1 and 3, which doubletree20, by means of the connecting-links 29 and 31, is provided with theswingletrees 30 and Secured to the bolt 14, passing thrmigh the maindoubletree 20, is the hinge-plate which at its remaining end ispivotally secured to a bolt 15, which bolt in turn passes through thetongue A of the wagon or implement. From this it will be seen that Isecure to the tongue A the bolt 15, and to this belt 15 is pivotallysecured the hinge-plate I). This hinge-plate in turn is provided withthe bolt 14:, which pivotally supports the main doubletree 20, to whichis secured at one end a swingletrec 28 and at the other end theauxiliary doubletree 20, secured by means of the clevises 18 and 19 andthe bolts 16 and 1'7, this auxiliary doubletree being provided with theswingletrees 30 and 32.

The tongue A is provided with the usual tongue-hounds 2, which aresecured to the usual wagon-hounds 5 by means of the governor-pin 3, heldby means of the nut 4:. Secured near the rear end' of the tongue A bymeans of the bolt 9 is the rear arm 0 of the spool-bracket B, as isshown in Figs. 1 and 2.

The forward arm a of this spool-bracket is secured to the tongue bymeans of the bolt 10, these arms a and 2 being provided with theperforations 9 and 10, adapted to receive the bolts 9 and 10, asdisclosed. Above this spool-bracket is provided with the hook 112, whilebelow and extending transversely across the bracket are the spools e andc, as shown in Fig. 5, where a bottom view of the spoolbracket isdisclosed.

In order to decrease the weight of the spoolbracket B, which ispreferably cast in iron, a portion of the material is removed, so thatthis bracket is provided with the bar 7 and the intermediate transverseportion 6, immediately adjacent which the spools c and c are secured, asdisclosed.

Now in securing the tongue A by means of the governor-pin thisgovernor-pin 3 is passed through the rear end of the tongue A, thencethrough one or more washers 8, interposed between the tongue and thespool a, thence through the spools a and c, and through the Too tongueand wagon hounds 2 and 5, as shown in Fig. 1. Extending from the hook 12is the draft-chain C, secured to the clevis 13, fastened to the pin 14L,as shown.

The tongue A, in order to strengthen the same, is provided with thereinforcing metallic strap a. i

From the construction as shown it will be noticed that the entire draftis placed upon the hook 12, which, by means of the draft-- chain C, issecured approximately centrally to the main doubletree which-doubletreein turn is pivotally secured by means of the hinge-plate b, fastened tothe tongue. This construction enables the three-horse evener beingsecured to the tongue in such a manner that one horse travels upon oneside of the tongue and two upon the opposite side, and between the threedraft-animals the load is equally distributed in such a manner that thetongue is advanced straight to the front, this construction insuring theload being drawn from the governor-pin.

These equalizers are made in various sizes to meet the differentrequirements and are sold without the tongue, being adapted to besecured to any ordinary Wagon or implement tongue. The tongue is securedto the tonguehounds 2 by the usual bar 1, as shown in Fig. 1. Now,having described my said invention, what I claim as new, and desire tosecure by United States Letters Patent, is

1. In a three-horse equalizer, the combination of the followinginstrumentalities, to-wit: a doubletree, a swingletree secured to oneend of said doubletree, an auxiliary doubletree secured to saidfirst-mentioned doubletree at the remaining end, a hinge-plate pivotallysecured to said first-mentioned doubletree near one end, saidhinge-plate at its remaining end being pivotally secured to a suitabletongue, a suitably-supported governor-pin, and an approximately C-shapedbracket secured to the vehicle-tongue, two perforated spools below saidbracket, aforesaid governor-pin passing through said spools, and meansto connect said first-mentioned doubletree to said bracket substantiallyas and for the purpose set forth.

2. The combination with a main doubletree, of a swingletree secured toone end of saiddoubletree, an auxiliary doubletree secured to theopposite end of said main doubletree, swingletrees secured to saiddoubletree, a hinge-plate pivotally secured to said main doubletree, asupporting-pin projecting from said hinge: plate, a chain projectingfrom said main doubletree, a bracket secured to said chain, and means tosecure said bracket to the wagontongue and the governor-pin of thewagontongue as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
